Getting node values as a string (XML)

[optik]

I'm using this to get a node value which works fine

$title=$title->item(0)->nodeValue;

But if I want to check whether $title is set I'm given an error saying $title is not a string even though it will echo as a string.

This isn't really my thing, but how are you trying to test and see if it's set?

[optik]

if($title){

}

Instead of...

echo $title;

Try testing with this...

var_dump( $title );

That will tell you what type of object the title is, as well as all of its contents.
